The active flux (AF) method is a finite volume method that evolves cell averages and point values at cell interfaces independently. In its original form, a piecewise quadratic reconstruction is adopted to achieve third-order accuracy in space. Due to the continuous reconstruction, spurious oscillations may appear near discontinuities, such that numerical solutions do not stay in admissible state set, e.g., violating maximum principle for scalar conservation laws, or leading to negative density or pressure for the compressible Euler equations. In this talk, I will present bound-preserving AF methods for one-dimensional hyperbolic conservation laws. The update of the cell average in the high-order active flux methods is rewritten as a combination of the cell average and some intermediate states with anti-diffusion fluxes, then the desired properties are enforced by limiting anti-diffusive fluxes that represent the difference between the high-order baseline scheme and a property-preserving approximation of Rusanov type. As there is no conservation requirement on the update of the point value, the high-order states obtained by the AF methods are directly blended with the states from the Rusanov scheme, such that the limited high-order states stay in the admissible state set. This talk will also introduce the Rusanov flux vector splitting for the point value update, which can cure the transonic issue caused by inaccurate estimation of the upwind direction based on the Jacobian splitting. Several extreme test cases will be shown to verify the accuracy, bound-preserving properties, and shock-capturing ability of our AF methods. This is a joint work with Wasilij Barsukow and Christian Klingenberg.
